Single-Center Review of Appropriateness and Utilization of Upper Endoscopy in Dyspepsia in the United States
Bibliographic record
Abstract
Background: We compared real-world practice of dyspepsia management to the new American College of Gastroenterology (ACG)/Canadian Association of Gastroenterology (CAG) guidelines 2017. Methods: We conducted a retrospective, observational study using administrative data to include patients undergoing esophagogastroduodenoscopy (EGD) for dyspepsia. Results: Out of 122 EGDs, only 30 (24.5%) were deemed appropriate per guidelines. Only 13 (14.1%) patients had undergone both Helicobacter pylori ( H. pylori ) test and treat and adequate proton pump inhibitor (PPI) before undergoing endoscopy. Nineteen (15.5%) patients had alarm symptoms (weight loss, melena and early satiety). Positivity rate of H. pylori was 36.3%, but only half completed treatment. Twenty-six patients (21.3%) had abnormalities on endoscopy, most commonly gastritis. There were no cases of gastric/esophageal cancer. Conclusions: The rate of inappropriate upper gastrointestinal endoscopy is higher than the existing literature, likely because of the stricter use of EGD in patients < 60 years. Only one in eight patients underwent the recommended workup before undergoing endoscopy. Gastroenterol Res. 2021;14(2):81-86 doi: https://doi.org/10.14740/gr1370

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
